The original well system I installed at my cabin included pressure tank with bladder,check valve at tank with manual air valve tapped into pump side, pitless adaptor at 2 feet below gound on solid rock, submersible pump with no check valve. After winter weekend use I would drain the tank and inside lines and then open the manual air line and the pump line would drain back to the pump. This worked great.
Recently I replace the old worn-out pump with a new pump with a built in check valve. I also added a brass orifice bleeder below the frost line at 5 feet below ground level for pipe drainage. However, now when I shut down the system as before and open the manual air valve instead of air being sucked into the pipe nothing happens.......the pipe doesn't drain. The air valve is not blocked, the ball in the bleeder orifice moves freely, the elevation from bleeder valve to tank is only 9 feet horizontal distance from well to tank is 15 feet, and the pipe from tank to pitless adapter slopes down hill.........it worked with the original system. I guess that I can remove the check valve in the pump and cap the orifice bleeder but I would still like to figure out why the present system won't drain. I welcome all suggestions.
